Teuchos::RCP<Epetra_Operator> createTridiagEpetraLinearOp	(	const int	globalDim,
		const double	diagScale,
		const bool	verbose,
		std::ostream &	out
	)

This function generates a tridiagonal linear operator using Epetra.

Specifically, this function returns a smart pointer to the matrix:

$A= \left[\begin{array}{rrrrrrrrrr} 2 a & -1 \\ -1 & 2 a & -1 \\ & \ddots & \ddots & \ddots \\ & & -1 & 2 a & -1 \\ & & & -1 & 2 a \end{array}\right]$

where diagScale is $a$ and globalDim is the glboal dimension of the matrix.
